How we handle sand mastic in Auldgirth
Silicone on a period window often looks wrong and isn’t always the right material. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. Common call-outs are for modern sealant on a period surround and mastic dropping out of the joint, on period & listed homes, timber door frames and sash and case windows.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill.
You are covered for a year from the day we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Keep modern sealant off the mastic
- Plan mastic work ahead of painting
- Ask us before painting near the mastic
- Inspect the joints round the windows every year or so
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.

Normally, yes. Once the silicone is out and the joint prepared, sand mastic is applied by hand.
Is consent needed for window work on a listed home?
Yes, it’s worth checking. Ask your local planning authority whether consent is needed for work on a listed home or in a conservation area.

It depends on the size of the job, but most jobs take anything from a few hours to a full day, depending on how many windows. We’ll tell you when we quote.
What we are called out for in Auldgirth
Shallow joints are a common cause. Mastic that is too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
People generally contact us when they notice one of these:
- Old cement repairs round a window that have failed
- Weathered mastic on the most exposed windows
- Gaps between timber frames and stone or brick
- Window mastic to renew ahead of painting
For jobs in and around Auldgirth, choosing the right material for each joint is as important as a tidy finish.
